FRANCIS LE BLON, OF BILLANCOURT, FRANCE.

CARBURETER FOR EXPLOSIVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 685,993, dated November 5, 1901.

Application filed November 21, 1900. Serial No.` 37,312. (No modell) To @ZZ whom t may concern/.-

Be it known that LFnnuois LE BLoN, a

citizen ofthe Republic of France, and a resi*` dent of Billancourt, Seine., France, have invented certain new and useful Improvements ject being to provide a carburetor in which the liquid hydrocarbon orV other liquid is constantly taken at the center of thelevel thereof whatever may be the position of the vehicle or apparatus.

With this object in View the invention consists in the construction, novel combination, and arrangement of partsA fully described and claimed hereinafter. f

In the accompanying drawings, Figure l is a vertical sectional view of av carbureter constructed in accordance with my invention. Fig. 2 is a plan view of same. Figs. 3 and 4 are detail views showingmodilied forms of shutters or obturators and means for actuating same. Fig. 5 shows a modified form of twyer or ejecting-nozzle. Fig. 6 shows a modified form of cover and outlet. Fig. 7 shows a plan view and vertical section of amodilied form of float. Fig. 8 is a view similar to Fig. 1 showing a modiied form of iioat and outlet. Fig. 9 illustrates a device applicable to 4my carbureter for heating the hydrocarbon after mixing it with air.

Like letters and numerals refer to like parts throughout all the views.

Referring to Fig. 1 of the drawings, A represents a suitably-shaped receptacle, the botl ceptacle D, the bottom of which is provided with a central hole, over which is suitably secured a vertical twyer or ejecting-nozzle F., the upper end of which is Iiush with the line K.

Secured over the receptacles A and Dis a hollow cover plate F, provided with peripherical holes H, adapted to` be controlled by means of a ring h, rotatably arranged around the cover F and provided with similar holes. Said holes serve for the admission of air into the carburetor. Secured at the center of the cover-plate F is the outlet-pipe I, the lower portion of which forms the mixing-chamber, extending downwardly to a point near the bottom of the receptacle D and through which the mixture of air and hydrocarbon passes to the motor. Arranged within the hollow cover F isa coil-pipe G, throughwhich is passed a part of the' exhaust-gases from the motor for the `purpose of heating the air entering the carbureter through the holes H.

When the motor is at its sucking period, the air entering the carburetery through the holes H and heated by the coil-pipeG passes downward through the annular space be-` tween the outlet-pipe I and the receptacle D and upward through the pipe AI and carries away the liquid contained in the central nozzle E. i i

From the drawings (dotted line K) it will be readily seen that the liquid is continually sucked away at the center of the level, notwithstanding the position of the apparatus.

Instead of attaching the valve C' directly to the iioat B said valve may be attached to a fulcrumed lever l, pivoted on a bracket 2 and pivotally connectedwitha lever 3, also fulcrumed on the bracket 2 and suitably connected at its free end with a rod 4, secured to the bottom of the iioat B. (See Figs. 3 and 4.) The construction increases the elhciency of the closing device operated by said float.

Instead of employing the nozzle E shown in Fig. 1 I may employ the device shown in Fig. 5,`t'ormed of a central tube E, made integral, with two branch conduits E E' turned one toward the other, whereby the jet is divided into two parts striking against each other, so as to be thoroughly pulverized and perfectly mingled with the air sucked into the carbureter.

The cover may be modified, as shown in Fig. G-that is, it may be provided with a tube-section 5, rotatably mounted in front of a branch pipe G and having a lateral opening adapted to register with said pipe 6, whereby the passage of gas through the latter may be intercepted when desired.

The lioat shown in Fig. 7 consists of an annular hollow casing 7, having a reduced portion 8. It will be understood that as the level of the liquid rises to the line N from its normal level at N the buoyan'cy of the float will be increased, thereby raising the inletclosing means to which it is connected. The number of shoulders (nine) may be augmented, so as to have a stepped form of float.

The. modification shown in Fig. S consists of a hollow upwardly-Haring iioat B, which is open at its upper end, the latter being above the level of the liquid and the bottom of which is provided with a central hole, over which is secured the ejecting-nozzle E. The inner receptacle D is open at its bottom, through which extends the outlet pipe I around said nozzle E. The interior of the `pipe I may be provided with a series of staglower end ofY said pipe I2 terminates in a plurality of tubes I3, curved upwardly and extending along the pipe I2 and out from the pipe I. Thus the exhaust-gases from the motor may be utilized for heating the mixture as it` is discharged from the twyer E, whereby petroleum or other hydrocarbon of inferior quality may be employed with great advantage.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is- I l. In the carbureter of the class described, the combination with a receptacle, a liquidinlet in the bottom of same, and a controlling-valve for said inlet, of a suitable oat within the receptacle and suitably connected with said controlling-valve, a second receptacle secured to and arranged within the outer receptacle, a suitable ejector at the center of the inner receptacle and communicating with the interior of the ou ter receptacle, a suitable cover above said receptacles, means for admitting air into the carbureter, an outlet-pi pe carried by said cover and extending around the ejector, meansfor-heating the air admitted into the carbureter, and means for heating the mixture of hydrocarbon and air, substantially as set forth. n

2. In a carbureter of the class described, the combination with a receptacle, a liquidinlet in the bottom of same, and a controllingvalve for said inlet, of a suitable float within the receptacle and suitably connected with said controlling-valve, a second receptacle secured to and arranged within the outer receptacle, a suitable ejector at the center of the inner receptacle and communicating with the interior of the outer receptacle, the upper end of said ejector being flush with the normal level of liquid within the outer receptacle, a suitable cover above said receptacles, means for admitting air into the carbureter, an outlet-pipe carried by said cover and extending around the ejector, means for heating the air admitted into the carbureter and means for heating the mixture of hydrocarbon and air, substantially as set forth.

In a carbureter of the class described, the combination with a receptacle, a liquidinlet in the bottom of same, and a controllingvalve for said inlet, of a suitable oat within the receptacle and suitably connected with said controlling-valve, a second receptacle secured to and arranged within the outer receptacle, a suitable ejector at the center of the inner receptacle and communicating with the interior of the outer receptacle, the upper end of said ejector being flush with the normal level of liquid within the outer receptacle, a hollow cover above said receptacles, holes in the wall of said cover through which air is adapted to be admitted into the carbureter, means for controlling said holes, a central outlet-pipe carried by the cover and extending around the ejector, means for heating the air admitted into the carbureter and means for heating the mixture of hydrocarbon and air, substantially as set forth.

4. In a carbureter ofthe class described, the combination with a receptacle, a liquidinlet in the bottom of'same, and a controllingvalve for said inlet, of a suitable float within the receptacle and suitably connected with said controlling-valve, a second receptacle secured to and arranged within the outer receptacle, a suitable ejector at the center of the. inner receptacle and communicating with the interior of the outer receptacle, the upper end of said ejector being flush with the normal level of liquid within the outer receptacle, a hollow cover above said receptacles, holes in the wall of said cover through which air is adapted to be admitted into the carbu-` reter, means for controlling said holes, a cen-- tral outlet-pipe carried by the cover and extending around the ejector, and a coil-pipe within the hollow cover and adapted to bel connected with the exhaust of themotor,` substantially as set forth.
